This invention relates to supporting means for advertisln s gns and the like, and has for its primary 0 ect and purpose to provide simply constructed and easily applied and adjusted means wherebyv advertising signs may be quickly mounted or erected in juxtaposed relation to temporary structures,such as sidewalk bridges used for the protection of pedestrians during the erection of buildings.

It is a further and more particular object of the invention to provide an improved form and construction of channel bar receiving bracket members whereby such bracket members may be readily adjusted upon the vertical tubular posts or standards of the temporary structure to position the channel bars for the reception of signs of various widths. t is another feature of'my invention to provide each of said bracket memberswith. adjustable means whereby the channel bars together with the sign supported at its edges in the channels thereof may be rigidly clamped and i 'i' i i, i t -l bracl'". fixed 1n p05 non 191% on O t 16 sleeve or tubular part 7 and a rectangular VViththe above and other objects in view, the invention consists in the n'nprovet sign supporting means and in the form, construcparts as will be hereinafter more fully described, illustrated in the accompanying drawings, and subsequently incorporated in the subjoined claims. v

In the drawing, wherein I have shown one simple and practical embodiment of my invention, and in which similar reference charactersdesignatecorresponding partsthroughout the several views,

Referring in detail to the drawing, in Fig. 1 thereof, I have shown parts of two vertical tubular posts or standards 5 which sup- 1929. Serial No. 374,048.

metal sidewalk bridge supporting structures whicharenowcoming into more or less general use, particularly lend themselves to such use. The vertical posts or standards 5 constituting parts of the supportingstructure are of light though strong metal tubing, providfed-in sections of suitable length which are coupled together. "On such cylindrical'tubular posts my improved sign supporting brackets constituting the "subject matter of this applicationmay {be readily applied and adjusted so as to support signs of various widthsat any deslredelevation above the ground or in predeterminedrelation to the 7 bridge platform.

As herein shown, each of the bracket members 6 consists of a metal casting having a section at one side of the sleeve 7. The outer tion and relative arrangement of its several findmtermedmte Walls of the ushaped part 8 of the casting are preferably provided ceninforcing rib 9 which at one of its ends, is merged into a substantially Vshapedlip or extension lOwhich in effect is a continuation of the common wallor web between the parts Tiand 8 of the casting. One sidefaco of this lip 10 is curvilinear andis a continuation of the inner surface of the sleeve? so that said face will closely 'fit the of the post 5.

The opposite, walls of cylindrical surface the part 6 of the bracket casting at the open side ofsaid U- shaped part are formed with the inwardly directed flanges 11 which provide guide seats or rests for the edges of the channel bar 12 which is adapted to befitted through said U-shaped parts 8 of the brackets on the spaced posts 5.

In the sleeve 7 opposite the part iof the bracket, a set screw 13 isthreaded. The wall -or web integrally connecting the parts 7 and 8. is provided at each sidethereof with a lateral extension or lug 14 in which a clamping screw 15 is threaded.

N then securely fixed in adjusted position by 135 tion on the upright,

tightening the set screws 13 againstthe wall of the post 5. The channel bars 12 are then passed through the U-shaped parts 8 of the" brackets on the spaced posts, with the open sides of said channel aligning with the space between the flanges 11 on'the walls of the bracket. The sign S is then slid longitudinally from one end of the structure into the channels of these bars 12. The screws 15 are channels bars 12 so as to thus securely clamp said channel bars as well as the edgeof the sign board in relatively fixed positions with respect to the supporting bracket. In this manner, it will be apparentthat the advertising signs may be easily and quickly erected upon such metallic supporting elements of the temporary bridge structure, and also as readily removed when the structure is to be dismounted. Further, the advertisements will be attractively displayed, the parts of the mounting itself being small and comparatively inconspicuous. I have herein shown and described an embodiment of my invention which has given very satisfactory results in practical use. Nevertheless, it is to be understood that the essential features of the device might also be incorporated in various other alternative structural forms, and I accordingly reserve the privilege of resorting to all such legitimate changes therein as may be fairly embodied within the spirit and scope of the invention as claimed.

I c a m 1. Sign supporting means including in combination with spaced uprights, a pair of bracket members adjustable relative to each other upon each upright, means carried by each bracket to clamp the same in fixed position on the upright, and each of said brackets having a substantially U-shaped part constituting a guiding and supporting means, channel bars to receive the edges of a sign engaged in the U-shaped parts of the corresponding brackets on the spaced uprights, and means carried by each bracket for rigidly fixing said channel bars with relation to the bracket members.
